	<h1>:: Reference :: Bounded Sizes ::</h1>

	Bounded sizes are used to restrict a layout element's initial size.
	They add context related layout information that the element
	does not or cannot provide. 
	To use a bounded size, you typically combine a component size 
	(min, pref or default) with a constant size as lower or upper bound.
	
	<p>
	For example, a well designed command button honors the
	button's label and icon size, but also uses a minimum width.
	The latter increases the design consistency and often
	makes it easier to click on buttons with short labels.
	A Swing <tt>JButton</tt> is used in different contexts:
	form, button bar, button stack, toolbar with icons, toolbar with texts,
	toolbar in large button mode, etc. Since the JButton (or the
	ButtonUI) can only provide a single <tt>preferredSize</tt>
	that often lacks the context. And so, the button lacks information
	about context-related layout requirements. 
	
	
	<h2>String Representations</h2>
	
	String representations for bounded sizes are used in
	the FormLayout constructors as well as in classes 
	<tt>ColumnSpec</tt>, <tt>RowSpec</tt> and <tt>Border</tt>.
	The string encodings allow to set only a lower <i>or</i>
	upper bound, where the related Java objects allow to set both
	bounds at the same time, which is needed rarely. 
	
<pre>
boundedSize ::=   [constantSize,componentSize]               // lower bound
                | [componentSize,constantSize]               // upper bound
                | [constantSize,componentSize,constantSize]  // lower and upper
                
                | MAX(constantSize;componentSize)            // lower bound (old)
                | MIN(constantSize;componentSize)            // upper bound (old)
</pre>


	<h2>Examples</h2><pre>
new ColumnSpec("[50dlu,pref]");     //  pref size with lower bound 50dlu

new RowSpec("[pref,80dlu]");        //  pref size with upper bound 80dlu

new FormLayout("[50dlu,pref], 4dlu, [100dlu,min]", 
               "p, 3dlu, p, 3dlu, [200dlu,p]:grow");
